Viewing The Status Of A Service Object - ICC XLTR-1000 Instruction Manual

ICC
Database Address
This is the starting address in the gateway's database that is used to mirror the
data on the network. The number of bytes allocated for the service object data is
determined by the data type and the number of objects in the service object.
Data Type
This field specifies how many bytes are used to store each object in the service
object. The data type also specifies whether the value should be treated as
signed or unsigned when converting it to a real number to send over the network.
Note that each data type has its own range limitations for what can be stored in
the database: 8 bits can store values up to 255, 16 bits can store values up to
65,535, and 32 bits can store values up to 4,294,967,295.
Multiplier
This field is the amount that associated network values are scaled by prior to
being stored into the database or after being retrieved from the database. Upon
retrieval from the database, the data is multiplied by the multiplier to produce a
network value. Similarly, network values are divided by the multiplier before being
stored into the database.
Note that the multiplier, coupled with the data type, imposes range limitations on
network data values. For example, if the data type is 8-bit and the multiplier is
0.5, then the network data can achieve a maximum value of only 127 (since 255
is the maximum value that can be stored in 8 bits in the database).
Function Codes
This field allows you to select which function code to use for a read or write. You
may also specify a read-only or a write-only service object by unchecking the
checkbox next to the write or the read function, respectively.
Note that some protocols only support one read and one write function code.

8.4.2 Viewing the Status of a Service Object

The gateway provides the user the ability to debug the configured service objects
while the device is running. When defining a service object, check the Reflect
Status checkbox and enter the database address to store the status information.
The status information is a 16-byte structure containing a transmission counter, a
receive counter, a receive error counter, the current status, and the last error of
the defined service object. This information is detailed in Appendix B: Status
Information. The data contained in the status information may be viewed over the
network on the other port of the gateway by mapping objects to the same
database address where the status information is stored.
Alternatively, the status can be viewed in the Monitor tab in the Status list of the
configuration utility. When a configuration that contains a service object status is
downloaded to the device, or uploaded from the device, that address is
